I wrote One piece (Manga by Eiichiro Oda) fanfiction.
Here is the summary:
When the Straw Hat crew docks at a quiet island for a simple supply run, everything goes wrong in record time — mostly because someone steals Luffy’s beloved hat. Zoro reacts with the calm, reasonable restraint of a man who immediately threatens to demolish half the town.
What follows is a chaotic chase through markets, rooftops, and ocean waves as the world’s most mismatched couple battles thieves, confusion, and each other’s stubbornness. Between sword fights and laughter, Luffy learns just how fiercely Zoro guards what he treasures — and Zoro learns that sometimes, protecting something precious means admitting how much it matters.
A lighthearted adventure of saltwater, straw, and the kind of love that survives explosions, teasing, and one very damp hat.
